In a major metropolitain market like Houston or Dallas? A red wagon is still way under the radar, especially if you aren't driving it like you are Mario Andretti.

My experience in Houston is that as long as you aren't doing seriously stupid stuff, things like driving 10-14 mph over the speed limit while having noncompliant license plates is still under the radar.

Don't antagonize and you will be fine no matter what color the car.

Ha! We live in the land of undocumentation.....above's normal here....
